Tunisia: ALKIMIA picks Veolia to deliver its HPD crystallization technologies

The ALKIMIA Group, a Tunisian chemical holding company specialized in the production of phosphate salts for industrial applications, relied on Veolia to deliver its HPD crystallization technologies at a new 25 000 tpy mono-ammonium phosphate (MAP) plant located in Gabes, Tunisia, said worldfertilizer.

Integrated to the plant, which will produce higher-value fertilizer for regional export, Veolia designed a circuit to process mono and diammonium phosphate solution through a double crystallization sequence using HPD PIC technology that allows for minimizing the waste purge and achieving higher production yields.

The production line includes solid-liquid centrifugal separation, drying, cooling, and screening systems to deliver a product with a large crystal size that has maximum purity (i.e. higher than 99% wt) and solubility (i.e. impurities concentration below 0.2% wt), according to the same source.

“We are pleased to help ALKIMIA diversify its product portfolio into higher-value products. This project at Gabes reflects the confidence of leading MAP producers in Veolia’s crystallization knowhow to deliver fully-soluble phosphorus fertilizers to a market hungry for sustaining crop yields amid increased water scarcity” stated Jim Brown, CEO of Veolia Water Technologies Americas.
